DRY-PAN FOR STEAM=BOILERS.

SPECIFICATION` forming part of Letters Patent No. 551,681, datedDecember 17, 1895. Ap'piimiou 5155 my 19,1595. s5fi51110.555,151. (Nomodel.)

-To @ZZ whom t may concern:

Be it known that I, EDWARD D. MEIER, la citizen of the United States,residing in the city of St. Louis, Missouri, have invented certain newand useful Improvements in Dry- Pans for Steam-Boilers; and I do herebydeclare that the following is a full, clear, and exact description oftheinvention, su ch as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in dry-pans or separators forsteam-boilers by means of which the steam in its passage from the boileris relieved from all water and moisture.

The effectual drying of steam involves its complete separation fromwater. NVhen steam is being made rapidly'the violent ebullition of thewater in the boiler, especially when the pressure is reduced by openinga valve or cock, or otherwise, throws up more or less spray, which,adhering to and following the walls of the boiler or drum, is liable tond its way into the dry pan or pipe and thus prevent or neutralize theaction of the pan-the thorough drying of the steam.

The main object of my invention is to avoid this difficulty; andtheinventionconsists in the means hereinafter described and claimedv foraccomplishing this end.

In the drawings, Figure 1 is a side view of my improved dry-pan. Fig. 2is an end view thereof partly in section, and Fig. 3 is a longitudinalsection on the line 3 3 of Fig. 2.

N is the dry-pan located at or near the top of the main shell orsteam-drum B, usually at the front of said drum. It is made in the shapeof a trough, which may be deeper at one end than at the other, thedeeper end fitting against the head of the steam-drum and its upperedges against the cylindrical walls thereof, the inner end being closedby a head ai. This pan may be made of wrought or cast metal in onepiece, or of 4a plurality of parts bolted or riveted together. I preferto build it of parts, because it enables me to introduce the separateparts through the manhole to be subsequently put together and connectedwith the drum. In order to avoid the expense of machine-finish to securea close joint between the edges of the pan and the shell of the drum, Iform grooves o in the edges, as shown, for the reception of suitablepacking, as asbestos rope or other heat-proof material. Openings Q areprovided in the sides of the dry-pan, well up toward the top, for theadmission of steam, and on the outside above and below these openingsare provided outwardly and downwardly projecting wings or guards P toprevent spray or water from entering the drypan during violentebullition.

Having now described my invention, what I claim is-v l. The improved drypan herein described connected with the boiler shell, the same beingprovided with openings in its walls for the admission of steam, and withdepending wings or plates opposite said openings to prevent the entranceof water or spray7 substantially as described.

2. The combination of a boiler or steam drum and a dry pan arranged inthe upper part thereof having openings in its walls for the admission ofsteam and outwardly and downwardly flaring wings above and below theopenings to prevent the entrance of water or sprayto the pan,substantially as described.

' In testimony whereof I affix my signature in the presence of twowitnesses.
